Hallo.
I've been experimenting with ssh2_exec.c, and while reading the
mailing list "sftp functions leaking memory?" thread, I realized this
example may suffer from the same problem.
On line 142, we've got this:
---
/* tell libssh2 we want it all done non-blocking */
libssh2_session_set_blocking(session, 0);
---
Then, on the "shutdown" tag, we've got this:
---
shutdown:
libssh2_session_disconnect(session,
"Normal Shutdown, Thank you for playing");
libssh2_session_free(session);
---
AFAICT, blocking is still off, so shutdown should be like this:
---
shutdown:
while (libssh2_session_disconnect(session, "Normal Shutdown, Thank
you for playing") == LIBSSH2_ERROR_EAGAIN)
;
while (libssh2_session_free(session) == LIBSSH2_ERROR_EAGAIN)
;
---
I've added no error cheking. Looking at session_disconnect() in
session.c, I was left with the impression that it only returns an
error if description (reason for disconnection) length > 256.
Otherwise, it always returns either LIBSSH2_ERROR_EAGAIN or 0.
Could you pls confirm if my reasoning is correct, so I may submit a
patch for this example?
Thanks.
Paulo Caetano
